Can You Complete Cube Field

Blender: the selector of instances grows ...

Continue work on the script ... for what is to me is actually already finished.

now defines an operator that can be used as a shortcut (screen.select_instances ()) and that I have assigned to "SHIFT + I"

There is an active selection and control over a report in the console and the main window blender.

Things to do: select by name. I do not want in any case it becomes a heavy tool windows and more: it is a small utility for internal whose merits must be fast and lightweight.

Sorry for writing a bit 'but I botched studied python last Thursday and Friday API blender, among other things, the API is subject to constant change and many examples on the site do not always work.

Here is the expanded code:

#! Bpy

"" "

Name: 'Select object instances'

Blender: 256

Group: 'Object'

Tooltip: 'Select object instances'

"" "

#Release 0.4

# - now the script is an operator that can be added as a shortcut

# under Preferences->Input->Screen

# - the script performs a control in order to check if there is something active

# - messages are printed in console (verbose output) and as report on the top

#

# TODO: select by name, i'd like to have a popup to choose the selection type.

EDIT: The script has been tested with a scene of over 2.7 million polygons and about 8000 instances of the object (cubes, cones, spheres, boxes)
